As country star Jason Aldean was playing, a 64-year-old Caucasian man named Stephen Paddock smashed out two windows of his suite on the 32nd floor of the Mandalay Bay Resort and Casino, which overlooked the concert grounds and opened fire.

Over the course of about 15 minutes, Paddock spent thousands of rounds with automatic rifles until police were able to locate him — at which point he committed suicide before police entered his room.

Police found at least 10 weapons inside the suite (some sources have said as many as 16). He had been staying at the hotel since Thursday, but staff said they saw nothing unusual about him or the room.

Later, they found an additional 18 firearms in his home, as well as explosives, several thousand rounds of ammunition, and some "electronic devices" which are being evaluated by authorities.

Authorities also reported finding ammonium nitrate, a key ingredient in explosive devices, in his car.

Another way in which the community has come together to help the victims? Several hotels and casinos — including Boyd Gaming (California, Fremont, Main Street Station), Station Casinos (The Palms, Red Rock, Palace Station), the South Point, and Siegel Suites — have all offered up free rooms and accommodations for family members of victims traveling to Vegas.

The fire department and law enforcement have set up a Family Assistance center for these families in the South Hall of the Las Vegas Convention Center.

They say they've had so many donations already they don't have room for any more.

A victims' fund was set up on GoFundMe by Clark County Commission Chair Steve Sisolak, and it's already raised over $1.7 million.

Well-placed sources tell us that Donald Trump Jr. and his wife, Vanessa, have been having marriage troubles for many, many years. In fact, we're told they almost broke up prior to her recent divorce filing because Don Jr. engaged in an extramarital relationship with Aubrey O'Day after she appeared on Celebrity Apprentice in 2012!
